| Abstract: | A kind of high performance concrete made of f ly ash composite additive with compressive strength grade of C60 to C70 is prepa red by using the raw materials available in Lanzhou. The important factors, incl uding the type of coarse aggregate, the amount of cement, fly ash composite addi tive, all of which will influence the compressive strength and workability of co ncrete, are analyzed. The principle of preparation of concretes with grade C60 t o C70 by using the local materials is pointed out. |
